Description

[Detailed description of the invention] [Industrial application field] The present invention is equipped with a pump in which the pump body and the motor body that constitute the pump are arranged separately on the inside and outside of the bathroom wall. It's about the bathroom.

[Prior Art] A jet pine surge pump that suctions hot water in a bathtub and sprays it into the bath from a spray nozzle communicating with a discharge port generally has a pump main body and a motor main body that are integrated. They were combined and placed inside the bathtub.

[Problems to be solved by the invention] However, in this type of pump, the rotating shaft of the pump main body and the rotating shaft of the motor main body are directly connected via a joint, so the pump main body of the pump There was a risk that hot water in the room could travel along the rotating shaft and enter the inside of the motor body.

Of course, a watertight sealing member such as an O-ring is interposed between the housing of the motor body and the rotating shaft, but as the rotating shaft rotates, the rotating shaft and the watertight sealing member come into sliding contact. Because of this, the watertight effect is not necessarily perfect, and it is impossible to completely prevent the hot water that is transmitted from the pump body side through the rotating shaft from penetrating into the motor body from between the rotating shaft and the watertight sealing member. This cannot be prevented, and the intrusion of hot water has a negative effect on the motor, and the flexibility is not necessarily satisfactory.

In addition, as mentioned above, since the pump is placed inside the bathtub, the inside of the bathtub becomes narrower and there is an inconvenience in that it is not possible to enjoy a relaxing massage while taking a bath. .

The present invention was made in order to solve the above-mentioned conventional problems, and its purpose is to separate the pump body and motor body that make up the pump into the outside and outside of the bathroom, and to separate the motor body. Rotation can be transmitted to the pump main body by magnetic force, completely preventing humidity in the bathroom from penetrating into the motor main body through the rotating shaft, and completely electrically insulating the pump. The objective is to provide a bathroom equipped with a pump that can be used in the bathroom.

[Means for Solving the Problems] The present invention employs the following means to achieve the above object. That is, in the present invention, a part of the bathroom peripheral wall is made of a non-magnetic plate that does not block magnetism, and inside and outside of the plate wall, there is a pump body inside and a motor body outside. The rotating part of the pump main body and the rotating part of the motor main body are opposed to each other in a non-contact state with the plate wall in between, and the rotating part of the motor main body is arranged on the opposing surface of both rotating parts. A means to solve the problem is to have a configuration in which a magnet is arranged to transmit power to the rotating part of the pump main body.

[Function] In a bathroom equipped with the pump of the present invention, the motor body and the pump body are arranged separately across a part of the surrounding wall of the bathroom, and the motor body is placed outside the bathroom. When the parts are started, the rotating parts provided in the motor body and the pump body, which are located close to each other and facing each other, are moved outside the bathroom by the magnetic force acting between the magnets arranged in the rotating parts. The rotation of the motor body is transmitted to the rotating part of the pump body which is magnetically coupled, and the pump rotates accordingly. This follow-up rotation starts the pump body, which is separated from the motor body, and allows the pump to be used in the bathroom. This pump is used not only for so-called in-bath pine surges such as jet pine surges and bubble pine surges in bathtubs, but also for supplying hot water to nearby washing machines.

[Example] Hereinafter, an example of the present invention will be described based on the drawings.

FIG. 1 shows a first embodiment of the invention. In the same figure, the surrounding walls of the bathroom are usually finished with tiles, etc., but in the bathroom of the present invention, the surrounding wall 1
is formed by a thin wall part 2, only a part of which is made of non-magnetic material such as plastic or glass and does not block magnetism, and the motor main body part 3 is placed outside the peripheral wall with the thin wall part 2 in between. , a pump main body 4 is disposed inside the peripheral wall.

The motor main body 3 includes a motor 5 and a motor 5.
